' ARCH-HANGER FOR FUTdNACES.

1 all whom it may concern:

Be it kiiown that I, HENRY E. WALLIS, a citizen of the United States, residing at Torre Iiautc, in the county of Vigo and State oi Indiana, have invented certain new and useful Improvements in Arch-Hangers for Furnaces, of which the following is a specification.

In the setting of chain-grate stokers, a lire brick ignition arch is suspended over the initial end of the structure Where, after it has become heated, it will subject the incoming fresh fuel to its radiated heat. The bricks of which this arch composed become broken and the hangers Warped so that difficulty has been heretofore experienced in replacing them because the hangers for suspending the bricks have been such as to interlock the several series and thus require a removal of the entire arch.

The object of mypresent invention to provide an improved hanger for arched bricks, the construction being such that a shade series bricks or a sing e hanger With es of bricks may be removed and ne'a bricks or a new hanger with its series of bricks inserted without disturbing the re" mainder of the arch.

The accompanying drawings illustrate my invention. 1

Figure 1 is a vertical section of a chainand setting provided with my inii I I proved arch hanger; Fig. 2,, a side elevation;

of said hanger in partiallvertical section hangers and associated bricks, the detach able hock being omitted, and Fig. 4, a per-l spective'view of the-detachable hook.

In the drawings, indidates channeldikej hanger comprising a pair oi; parallel de'pendd ing fingers or flanges 11]11 each, provided; at its lower edge with an! inturned lug ori flange 12 adapted to be received in the sidel grooves 13 of the arch bricks 14. Each? hanger 3 is provided at one end with a% hook to and at the opposite end is provided I Specification of Letters Patent.

with an openin 16 through which may be projected a 11007117. Hm k 17 is prov ded at its inner end with a base 18 adapted to fit Within a socket 19 tonne d in hanger 10 at the inner end of opening 1 3. The setting is provided transverse beams 20 and 2 the stokci; structure in the i'sual Well known manner. As many hangeis ides may be necessary'are then supported upon the beams 20 and 21, the hooks resting upon the foot of beam While h the foot of beam 21. The bricks 14 are slipped into the hangers 10, as clearly shown in Fig. 3, and each series oi bricks abuts the adjacent series so as to tully protect the hangers from the 'heat of this fire. When the bricks become broken theghangers will be come Warped by the heat aid in order to re' place any hanger it is merely necessary to swing book 17 of the injured hanger so as to with a tilt of iarrange above n. 21, whereupon led down away sturbing the remainder of the arch.

l claun as my invention:

Joke 17 rest upon 1. 13.1 arch-hanger, comprising a main body having a pair of depending fingers each provided with an inwardly projecting lug, and a pair of hanger hooks carried by the main body, one of said hookls being movable.

An arch-hanger, comprising a main body having ape-i1 of ,deperrdingfingers each provided with an inwardly projecting lug,

an inwardly projecting hook carried by said body atone end, and a movable hook projected through the main body at the other end;

In Witness whereof, I, have hereunto set my hand and seal at Terre Haute, Indiana, this the 8th day of April, A. D. one thousand nine hundred and seven.
